Found an answer. The problem seems to be that I was sending a map of
parameter values through the execute method:
Map<String,Object> params = new HashMap<String,Object>();
params.put("a", 3);
params.put("b", 5);
Object result = fun.execute(params);
When what I needed to do was just pass the values:
Object result = fun.execute(3,5);
